To all whom, t 'may concern: i

Be it known that l, JOHN W. RAP?, a piti; zen of the United States,and.- a resident of Flushing, borough of Queens, city and State of NewYork, have invented Tvcertain new and useful improvements in Mstal Doorsand Similar Devices, of whichthe following is a specification. i

My invention relates to improvements in metal doors and similar devicesand is espe eially well adapted for what are commonly known as doors ofthe hollori7 metal type.

in the accompanying drawings Figurelis s. front View of the top'pprtionof er door embodying the improved formof my invention, and partly brokenaway; Fig. H is a horizontal cross section on the line A-A of Fig. l; Fig. lll is an enlarged view in cross section of a top or bottom rail orstile; Fig. .lV the same as Figi lll, showing my preferred form oflocking key inposition; F ig. V .is a horizontal cross section View online lh-B of Fig. l;vFig. Vl illustrates my preferred method of securinga molding to a rail or stile and alsofor .retaining in position a panel;Fig. VH 'illustrates asimilar construction, but modified, to permit ofthe ready removal of the panel, and especially adapted wherel the panelis of glass or Aother material so readily destructihle, which it mightbe desired to move or change; 'Fig VIH is a cross sectionon the vlineC-C `of Fig. 1X; Fig. iX. is a front view of a door embodying myinvention in a modified form; Fig. X is a cross section on the line D-Dof Fig. IX, and Fig. Xl is a' cross section on the line lil-#E of Fig.IX, where again the panel is Vshown to 'be of glass and easilyremovable.

ln these drawings similar reference characters designatecorrespondingparts.

Referring now to the preferred form of my invention yillustrated inVthese drawings, iii-H, designate the Stiles of the door, and J, J, thetop and bottom rails. Obviously the construction of the top and' bottomrails is the same and the construction of the two" Stiles is the same,and the construetiodof the Stiles is the same as that of the top andbottom rails excepting 'at the junction point of a stilewith' a rail.

Each rail and each stile is preferably hollowl and substantiallyrectangular in cross section, having parallel side plates, an integraledge or end plate and provided at its inner edge with two lips orfdanges desig- ,Speeilcation of Letters Patent? Y Patented Jaa. 1e,1915. me.y seggi No. 570,269.

hated hik. the case of stiles and j-j in the case of top'--and,bottomrails. The lips or Aflanges are alsofpreferably integral with andarranged to project from cross plates or inwardly bent'portions integralwith side platesand extending toward `each other so as to bridge a partof the distanee between the side plates, and to provide a slot or groove.in the lengthwise edge' opposite to the outer edge or. end plate/'ofthe rail or stile. In the case of the stil'es these projecting lips.li-7L" are used in" conjunction with a key to secure a molding to theinner edge of the Stiles, and also to eli'ect the junction between theStiles and the top and bottom rails. For example, as illustrated in Fig.11,-the lips or flanges h-t of the stile H are inserted between theinwardly projecting lips or flanges 7.--c of a ymolding K.

' M designates what l call a key, shown as made of one piece of metalbent to form a back plate, m, and two tongues m1 projecting therefrom,and bent over and backward at their outer ends to form securing clips m2m2. l

The lips or flanges t-c of the molding K having been .slipped over thelips or flanges L-L of the stile H, and arranged to the desiredposition, my key M is then inserted as indicated in Figs. Il and IV withthe tongues m1-m1 intermediate the flanges or lips L-L of the stile H,with the back plate min Contact with the inner surface ofthe inner endof the stile, and with the bent over rretainng clips fm2-m2 of the keysurrounding and in contact with the 'ilanges or lips /r-: of the moldingK. This key is then driven in any suitable manner throughout the lengthof the stile or at least throughout that portion of the stile to whichit is desired to secure a molding. The molding is secured to the top andbottom rails in a precisely similar manner. y

Fig. V illustrates my preferred method of `securing the stiles and railstogether, y where the flanges or lips laf-71. on the inner edge of thestile continue throughout the entire length of the. latter` and the keyM i2-ff, between which are inserted the out Wardly projecting lips oranges t-h of the vstile H. The key K is then inserted in 16 n peill'llll'lCel the same manner as already described with regard to Fig. IIand driven through first to secure one rail to the stile, and second tosecure themolding to the stile, and finally to secure they other'. railto thestile.` As the f molding has already been secured to the inner'edge ofthe top and bottom rails and cut at the corners `at thev desiredangle, the molding on the rails will be forced into proper position withregard to the molding of the stiles as the key is driven'home. Thecorners of the molding may then be welded together by electric weldingorany other suitable method, or be 'treated in any other way to give asmooth and finished apthe stile, if the saine, has been left open topermitl 'of the driving of the key, or if hole haslbeen "made or leftfor this' purpose`,'tl'ie same may be closed by'welding a piece of metalover thevsameeorinany other f Lsuitable manner.

ranged withinv the groove Kleef a molding K. As the metal of the'molding is` preferably rather thin and resilientthe.driving home of thekeyM` should result in the lpanel being gripped rby-tlienvalls of thegroove K1. .i f.

IVhereglass or` other destructible mate. rial is used as the panel orwhere for any other reason it may be necessary or desirf kable to makethe panel removable, I prefer to 'use a construction suchas isillustrated in I Fig.v VII, wliicliis the same in all respects as thatillustrated in Figs.. II and VI with the exception that themolding isbent to formonlv one side and the back wall of the groove K1 integral`with thegmolding. ,The

other side wall of the groove is `formed of H a separate piece ofinetaldesignated in Fig.

VII byc5 and removablyfsecured,to'the rest of the molding inany suitablemanner `as'by a screw Z.. i

In Figs. VIIIf- IXf-X and XI, I have .illustrated what maybe called aninversion vorreversal of tliecoustruction and nietliod emplovedin thefigures so far described.' Fig. VIII shows the joining of arail toastile where the lips or aiige's yt-y2 of the rail .I project outwardlyand those lr-4h of the stile Il proiect inwardly, and 'where the key hasvits backm rarranged within the rail yand. its securing clips project?'lng into the Vinterior 0f the stile.

Figs. andXI illustrate respectively the'invei'ted method ofsecuringamoldingand a'non After theparts'have been secured in place as alreadydescribed, a top plate may be welded Vover the open end of removablepanel (Fig. X) and a removable panel such as glass Fig. XI). In thesefigures the stile H has its lips or flangesi-h projecting inwardly,whereas the lips ork flanges iti-lc kof the molding K project outwardly.Obviously the'key M is inserted as described with regard to Fig. VIII,and then driven down throughout the length of the stile to secure Athetop and bottoni rail and the molding and the various panels thereto.This inverted form is peculiarly adapted to cases where the molding issmall or where there is' vinsuflicient space in the molding to permit ofthe ready insertion of the 'tongues and securing clips of the key.

If intermediate rails, such as those designated J1 and J2 ofAFig. IX areused, their ends are provided with lips or flanges pro jecting eitherinwardly or outwardly, and secured in the saine manner as the top `andbottom rails.y
